CORN=PLNTER- SPECIFICATION forming part of Letters Patent No. 378,164,dated FebraaryZl, 1888.

Application filed Novemlycr, 1887. Serial Xo. 236,162. (No model-l Toall wtont t may concern:

Be it known that I, JOHN DE BUTTS, a citizen of the United States,residing at Centreville, in the county of Queen Anne and State ofMaryland, have invented certain new and useful Improvements inCornPlanters; and I do hereby declare the following to he a full, clear,and exact description of the invention, such as will ena-ble othersskilled in the art to which it appertains to nia-lie and use the same.

This invention is an improvement on my Patent No. 307,183, dated October28,1S8ihand has for its object, chietly, to prevent the seedslide frombeing withdrawn too soon or jest-led out of its place. To effect thisobject I eniploy devices for automatically locking and unlocking theshaft which operates said slide and arrange these so that it may hecaused to remain stationary, except when the slide ought to be moved inor ont. I also provide for more iirmly supporting said shaft and itsattach ments than in the patent aforesaid.

In the accompanying drawings, Figure l represents a plan view of acorn-planter embodying my invention. Fig. 2 represents a detail view inside elevation, enlarged, ofthe slide-operating shaft and the devicesfor automatically locking and unlocking it, with the supports therefor.Fig. 3 represents a detail perspective view, also enlarged, of thepinion carried hy said shaft, the locking devices therefor, and thesegment-carrying wheel,with one ofthe flanges thereon in the act ofholding said devices out of locking position. Figs. 4, 5, and G areadditional detail views.

A designates the axle ofthe corn-planter, to which is attached the mainframe B, having a supplemental or seed l'raine, C, hinged to its forwardend. To this latter frame the pole D is attached, and said frame issupported at each side by shoes E, above which thc seedboxes F arearranged.

G designates the seed-slide, which reci procates transversely of themachine, its ends entering said seed-boxes and alternately coveringanduncovering their outlets after the usual manner. This slide is operatedhy a short lever, II,which is pivotcd at the forward end to said frame Cand attached near its middle to said slide. The other end of said leveris attached to a transverselyoperating pitman, I, which receives motionfrom a longitudinal shaft, J, mounted in hearings j j, and provided witha crank-arm, K, and wrist-pin k, to which the outer end of said pitnianis loosely secured. The hearings j j are snpport-ed by a plate or har,L,which is arranged longitudinally of the machine, and supports also thehearings l Z of the shaft l of a gearwheel, BI, turning with said shaft.In my former patent aforesaid this har L had its for4 ward end atttachedto a rigid supplemental har; hut for greater strengtlrand simplicity Inow extend the said plate Lto the front or supplemental frame, C, andpivot its forward end thereon. Said forward end is hinged to the body ofthe plate or bar to rise and fall with said frame. The rear end of saidhar or plate Lis free to move horizontally for a short dist-ance in aguideway, G, attached tothe under side et' axle A, and is provided witha vertical shifting lever, Rwhich is pivoted to said axle. This leverworks above its pivotal point in a slotted piece, Q, which has anenlargement of its slot at its inner end, q, forming a shoulder forengaging and locking said lever at that point.

It It designate the transporting-whecls of the planter, the latter wheelbeing also the drivin g-wheel of the seed-dropping apparatus. To effectthis, the said wheel R has attached to its side or formed therewith agear-wheel, S, which meshes with the wheel M aforesaid, when the latteris thrown into its outermost position, by turning the outer end of leverP inward, as aforesaid. The 'forward face of said wheel M is provided atintervals with series of screwholes m, for the attachment of segments T,one segment to each series. These segments are internally toothed andprovided with screws t, which pass through holes in them .and enter thesaid screw-tapped holes or recesses m. On the rear end of shaft .I isiixed a pinion, U, which meshes with said segments. The wheel l'lI ispreferably adapted to receive four of these segments, and all of thesemay be used together, or any less number, as stated in my patentaforesaid. As each of these segments eoxncs in contact with said pinionand turns it., the seed-slide G is caused to reciprocate by the actionof shaft J, pin 7c, pitman I, and lever H. To guard against improperniotion oi said slide, I provide the pinion U with recesses il, in itsfront face, and arrange a pin,

lOO

2` avais@ o, on a fixed spring, V, so that the action lof the latterwill force said spring into one of said recesses Whenever it comesopposite the pin. Each of the segments Tis provided with a raised ange,XV, which comes in contact, as it revolves, with an anti-frictionroller, w, also carried by said spring on an arm of the latter,extending outwardly therefrom, and forces back said spring, so as toremove said pin from the recess u. The said flange holds said pin out ofengagement With said recess until the segment has ceased to operate onthe pinion U and the seedslide has consequently ended its reciprocatingmotion. The iiange then passes from the roller w, the pin t is forced byspring V into the next recess a, and the shaft J and feed-slide arethereby locked motionless until the next segment and flange come roundto repeat the operation.

Having thus described my inventiomwhat I claim as new, and desire tosecure by Letters Patent, is-

1. In combination with a seed-slide and a shaft for operating the same,a locking device d engaging an attachment of said shaft and a rotatingtoothed segment which meshes with a gear-wheel for driving said shaft,said segment being also provided with a flange for releasing saidloclting device, substantially as set forth.-

2. In combination with a seed-slide and a shaft for operating the same,a locking device engaging an attachment of said shaft, gearing fordriving said shaft, and a rotating flange having an inclined face whichreleases said locking device, substantially as set forth.

3. In combination with a seed-slide and a shaft for operating the same,a locking device engaging an attachment of said shaft, a pinion fixed onsaid shaft, and awheel provided with a series of segments whichsuccessively engage said pinion, each segment being provided with aflange for removing said locking device from engagement, for the purposeset forth.

4.-. In combination With a seed-slide anda shaft for operating the same,a pinion turning with said shaft and having arecess formed therein, apin arranged to enter said recess, a spring to which said pin isattached and which is provided with an outwardly-extending arm, NV', anda rotating segment provided with a fiange or projection arranged to actagainst said arm and withdraw said pin from said pinion, substantiallyas set forth.

5. A segment having internal; teeth and a raised flange, in combinationwith a wheel to which said segment is attached, a pinion meshing withsaid segment and having recesses a,

a spring provided with a pin for entering said recesses, a roller to bestruck by said iiange for withdrawing said pin, a shaft turning withsaid pinion, and a seed-slide operated by said shaft, substantially asset forth.

6. In combination with the frame A and hinged supplemental frame C, theplate or bar L, pivoted at its front end to the latter frame, the shaftturning in bearings thereon, the seedslides and connections bet-Weenthem and said shaft, the lever for moving said bar laterally, and theoperating-gearing which is separated 0r brought together by this lateralmotion, substantially as set forth.

7. The bar L, laterally movable at one end and pivoted at the other, incombination with a hinged frame, G, to which its pivoted end isattached, a shaft mounted in bearings on said bar, the feed-slides, andsupporting and driving mechanism, substantially as set forth.

In testimony whereof I at'tix my signature in presence of two witnesses.

JNO. DE BUTTS.
